Get the Heat Out!

Rectifier Assembly Design Considerations - Thermal Management


When I think of rectifier designs, high voltage stacks, single phase bridges, and three phase bridges come to mind. These are all made using strings of high voltage, discrete diodes soldered together.

Thermal management is critical to long-life , and reliablity. 

Here are several methods to help you 'get the heat out'...Continue >>
